[0019] The application will be described in further detail below with reference to the drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the application and cannot be understood as limiting the scope of protection of the application. Those skilled in the art can make some non-essential improvements and adjustments to the application according to the above application content.

[0020] As shown in Figure 1 、 Figure 2 A sealing structure for a rocker faucet, comprising a faucet body 1, the faucet body 1 is provided with a water inlet and a water outlet, the faucet body 1 is internally provided with a control valve (not shown in the figure), the control valve is signal connected with a control element, further comprising a rocker 5, the output end of the rocker 5 is signal connected with a signal processing module, the output end of the signal processing module is connected with the control element, the rocker 5 comprises a control rod and a base, a cavity 2 is formed on the faucet body 1, the cavity 2 is communicated with the external environment through an opening 3, the base is arranged in the cavity 2, further comprising a sealing gasket 4, the control rod is arranged through the sealing gasket 4, and the sealing gasket 4 is used for sealing the cavity 2.

[0021] In this embodiment, the faucet body 1 is internally provided with a water inlet and a water outlet, and water flows in and out through the two ports;

[0022] The rocker 5 is used for user input, the user rotates the rocker 5, controls different flow rates through different angle positions of the rocker 5, and different positions of the rocker 5 generate different voltage signals, which are transmitted to the signal processing module through a potentiometer or a sensor. It should be noted that the rocker 5 usually contains a built-in potentiometer. The potentiometer is a variable resistor, which has a sliding contact inside. When the user moves the rocker, the sliding contact moves on the resistor, thereby changing the resistance value. This change causes the output voltage of the potentiometer (the voltage between the power supply and the ground) to change with the position of the rocker. Specifically:

[0023] When the rocker is at a certain limit position, the output voltage of the potentiometer approaches the maximum value; when the rocker is at another limit position, the output voltage approaches the minimum value; and when the rocker is at an intermediate position, the output voltage will be a value between the maximum value and the minimum value;

[0024] The signal processing module receives the input signal of the rocker 5, judges the size of the water flow according to the preset algorithm, and sends the signal to the control component, which controls the opening of the control valve to adjust the water flow. The control valve is located inside the faucet, and the water flow is opened or closed through the electric signal. When the signal processing module sends the signal, the control component adjusts the state of the control valve according to the received signal, thereby controlling the on-off and flow of the water flow. For example, when the rocker moves upwards, the signal processing module may send a signal to gradually open the control valve and increase the water flow. Conversely, when moving downwards, the control valve is closed to reduce the water flow.

[0025] The sealing gasket 4 is arranged at the opening 3 to protect the electronic components in the cavity 2 from water splashing into the cavity 2 during use, which affects the normal operation of the electronic components. A circular hole can be formed in the middle of the sealing gasket 4, and the control rod passes through the circular hole. It should be noted that the circular hole around the control rod should be tightly fitted with the control rod, so that even if the control rod swings, no gap is generated, thereby effectively protecting the components in the cavity 2.

[0026] The control valve can be an electromagnetic valve or a pneumatic valve, and the signal processing module can be a host or a microcontroller, as long as it can realize signal control. Here, it is not repeated.

[0027] In the specific implementation, the sealing gasket 4 is made of flexible material and has a pleated structure, and the area of the sealing gasket 4 is greater than the area of the opening 3.

[0028] The sealing gasket 4 can be laid on the opening 3, and the periphery is fixedly connected with the surface of the faucet body 1.

[0029] In actual use, the control rod needs to swing in different directions. The sealing gasket 4 is made of flexible material such as rubber, and the pleated structure can bend, stretch or compress within a certain range, which facilitates the swinging of the control rod in different directions and the stretching and contraction of the rocker. The sealing gasket will deform with the movement of the rocker. In this way, the sealing gasket 4 can play a waterproof effect regardless of the state of the rocker. The sealing gasket 4 can be fixedly arranged on the opening 3 or can be connected by clamping.

[0030] The structure of the sealing gasket 4 is not limited to the structure shown in the figure. The sealing gasket 4 is provided with a groove, which can also be provided with an upper convex shape or a wave shape.

[0032] The sealing block 6 can be sleeved in the opening 3, the sealing gasket 4 is arranged around the sealing block 6 and the opening 3, and the sealing block 6 is clamped between the outer wall of the sealing block 6 and the inner wall of the opening 3, so that the sealing effect is achieved, and water leakage is prevented.

[0033] The sealing gasket 4 can also be above the opening 3, and the sealing block 6 is above the sealing gasket 4, and the sealing gasket is fixedly and tightly sealed with the body 1 to achieve sealing (not shown in the figure).

[0034] In the embodiment, as shown in the figure, Figure 4 The sealing block 6 further comprises a connecting portion 601, a through hole 602 is formed in the connecting portion 601, a screw column 7 is arranged in the cavity 2, the sealing block 6 is connected with the screw column 7 through a screw 8, and the sealing gasket 4 is tightly pressed with the faucet body 1.

[0035] In actual use, the screw 8 cooperates with the screw column 7 to make the upper edge of the sealing block 6 in contact with the sealing gasket 4 around and tightly abut against the inner wall of the cavity 2, so that the sealing gasket 4 is prevented from falling off and a gap is prevented from occurring, thereby improving the sealing effect.

[0036] The screw column 7 and the faucet body 1 can be integrated, that is, the faucet body 1 has the screw column 7 which can be fixed with the sealing block 6 through the screw.

[0037] In the embodiment, as shown in the figure, Figure 3 , Figure 5 The end of the control rod away from the faucet body 1 is rotationally provided with a knob 9, the knob 9 is provided with an angle sensor 10, and the knob 9 is used to control the water temperature.

[0038] In actual use, the user sets the desired water temperature through the knob 9, the angle sensor 10 detects the position of the knob and converts it into a corresponding electrical signal, the signal processing module receives the signal from the angle sensor 10, calculates the required proportion of hot water and cold water or the power of the device to achieve the desired water temperature, and sends a signal to the control device through the signal processing module to adjust the control valve to control the on-off state and opening degree, so as to adjust the flow of cold water and hot water. According to the adjustment of the control valve, the cold water and the hot water are mixed in the set proportion, and finally flow out through the water outlet to form the water temperature required by the user.

[0039] In the embodiment, the angle sensor 10 is an encoder.

[0040] The encoder can adopt an incremental encoder to provide high-precision angle measurement, for example, an EC35 incremental encoder which is miniaturized and suitable for limited space applications and provides multiple resolution options and high reliability.

[0041] As shown in Figure 5 The arrow direction is the lever direction and the knob 9 rotation direction, the water temperature is controlled by rotating the knob 9, the knob 9 rotation direction is not limited, can be clockwise or counterclockwise; the water flow size is controlled by the lever, the lever direction is not limited in the application.
